WATER-HEATERQ SPECIFICATION forming part of Letters Patent No. 408,893, dated August 13, 1889.

Application filed June 1, 1889. Serial No. 312.891, (No model.)

To cZZ whom, it may conccrn:

Be it known that we, THOMAs G. G. MOUAT and LEE BURT, citizens of the United States, residing at Detroit, county of XVayne, State of Michigan, have invented a certain new and useful Improvement in a Hot-WVater Heater; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to certain new and useful improvements in hot-water heaters, and has reference more particularly to improvements in the line of. such heaters as that enbodied in the pending application of Thomas G. G. Monat, Serial No. 303,39l, wherein a series of sections extending across the combustion-chamber of a furnace communicate, intermediate their extremities, with awater-chamber above said chanber provided with drop-tubes, all as more fully explained in said application.

The objects of our present invention contemplate, first, the provision of separate Water -chanbers communicating, respectively, with separate sections beneath and provided with drop-tubes, as hereinafterset forth; second, the construction and union of the respective sections and their communicating water-chambers in such a manner that each section, with its connected chamber and droptubes, may be separable from the remaining series of sections and chambers, so that each section, with its corresponding chamber, may be independently removed or united with the remainder; third, the Construction of the said sections with flanges to meet together andcompel the products of combustion to pass laterally from the combustion-chamber and thence upward over the sections and about the marginal as well as the central droptubes to more perfectly insure the proper distribution ot heat over and about all parts of the heater; fourth, the independent construction and arrangement of the separate sections and separate communicating chambers in such a manner that the heat therefrom may be led independently to any desired part of the building to be heated; fifth, to provide a novel hot-water heater wherein the production ot steam is rendered inpossible. .Our invention, sixth, also contemplates the general Construction, combination, and 'arrangements of devices and appliances, more 'fully hereinafter described and set forth in the clains, and more eXplicitly illustrated in the accompanying drawings, in which i Figure 1 is a vertical section of a device embodying our invention. Fig. 2 is also a vertical section of the same at right angles to that shown in Fig. 1. Fig. 3 is a perspective showing` two sections and their communicating chambers constructed to deflect the products of combnstion to the sides of the combustion-chainber.

We Carry out our invention as follows:

A denotes any suitable inclosing-wall of a furnace; B, any suitable grate in the combustion-chamber of the furnace.

C represents a water-section extending across the combustion-chanber, preferably rising toward the center of the section, although we do not confine ourselves to this Construction.

-C' denotes an infioW-pipe communication with each section, and 0 a return-pipe. The infiow-pipes and return-pipes may lead from a common header or manifold, as shown at 0 and 0 respectively.

D is a water-chamber located above a corresponding section C and communicating therewith through one or more pipes E, leading upward from the said section intermediate its ends, the Construction and arrangement being such that water entering the section will in all cases be compelled to pass to '90 IOO the chamher to pass first to the extremities of the chamber before it can pass to the linepipes therefrom, thus causing the drop-pipes to be always filled, and conpellin g an eflicient circulation of the water and the retention of the same over the fueLbcd tor the longest practicable period in order to be most thoroughly heated thereby.

The exit-pipes from the water-chanbers I), where a series of them are enployed, may, if desired, be engaged with a comnon manifold, as at Il II', at each end of said chambers; or the said cXit-pipes may separatcly lead to a special cireuit. lVe contenplate either of these methods of communicating the chambers with the line-pipes, as may be preferred, as coming within the scope of our invention. XVc prefer also to construct or provide the separate sections with fianges or ribs e to close up the space between the upper edges of the sections and so compel the products of conbustion to pass to the extremities of the sections in order to find their escape upward; or, instead of so constructing the sections with lianges c for this purpose, the individual chambers may be provided with a flange d, to close the space between the upper adjacent edges ot the chambers and so eompcl the products of combustion to pass to the extremities of the chambers before finding their exit from the combustion-chamber, and consequently causing the heat to be distributed in an efficient nanner throughout the eonbustion-chamber and about all parts of the apparatus. Should the sections be provided with said iianges, the chambers may be constructed without them, and vice versa; or the flanges may be altogether omitted without dcparting from our invention.

In a hcater constructcd in this nanner it is evident that the water nust at all times cover every part of the heater froni its entrance into the sections C to its exit through the eutletpipes at the extremities of the chambers D, and so that when the water is in circulation the fornation of steam is effectually preventcd. Itis obvious also that the water froni any chamber of the series may be led to any special circuit of the line-pipes desired. The water being independentlyheated in the separate sections and communicating chambers may be also independently distributed. In this manner the heat may be etectually distributed to every part of the house. The

water from any given clamber returning to the manifold U* has its temperature raised before its entrance again into the hcater.

\Vhat we claim as our invention is 1. In a hot-water heater, the eonbination, with an individual section (i, extendiu g across the combustionchanbcr, of' an individual water-chamber D, provided with outlets to the lie-pipcs and eonuunicating With said section intermediate the extreinities of said section, said section and conununicating chamber independently renovable 'from the heater, substantially as set forth.

2. In a hot-water heater, the eonbination, with an individual section C, extending across the eombustion-chanber, of an individual water-chamber D, provided with drop-tubes and outlets to the line-pipes and communicating with said section intermediate the extremities of the section, said section and communieating chanbcr independently removable from theheater, substantially as set forth.

In a hot-water heater, the eombination, with an individual section C, extending across the fuel-bed, of an individual watcr-clamber D,con1municatin g thercwith,th e one provided with fianges to deilcct the products of eonbustion, the other open at its sides to allow the passage of the products of combuston, substantially as set forth.

4. In a hot-water heater, the eonbination, with a series of individual sections C, of a sc- 'ies of individual water-chambers D, each connnunicating with acorresponding section, each section with its ehanber separablc from the remaining sections and chambers of the series, substantially as set forth.

5. In' a hot-water heater, the eonbination, with a series of individual sections C, extendingaeross the combustion-chamber, of a series of individual water-chambers D, each communicating independently with a corresponding section, said chambers provided with droptubes and outlet-pipes leading from the extremities of said chambers, substantially as set fo'th. 4

6. In a hot-water heater, the combination, with a series of individual sections (i, of aserics of individual water-chambers D,eaeh eonmunicating, respectively, with a corrcsponding section, outlet-pipes leading from said chambers, each chamber conncctin g wi th separate cireuits, substantially as set torth.

In testinoywhereof we sign this specification in the presence ot' two witnesses.
